Evaluation of CMIP6 models performing on rainfall seasons and moisture tracking simulation in Yangtze River Basin

This study evaluates the performance of the CMIP6 models in simulating monsoon rainfall and moisture tracking in the Yangtze River basin. The findings reveal varying degrees of accuracy across different regions of the basin during the monsoon period. Downstream and midstream regions demonstrate higher accuracy, whereas upstream areas exhibit...

De-Landing Growth: Framing Alternative Perspectives to Evolution in Mumbai

The prevalent paradigm of development in Mumbai is defined by anthropogenic processes aimed at building more. Manifesting in the form of inland architectonic augmentations or outward reclamations into the sea, these interventions are dissociated/incongruently positioned in the territorial ecosystem. Thereby altering natural cycles, disrupting...

Use of Remote-Sensing-Based Global Products for Agricultural Drought Assessment in the Narmada Basin, India

Droughts exert severe impacts on the environment, economy, and society. The south Asian region is vulnerable to droughts and the Indian sub-continent is one of the most vulnerable in the region to frequent drought disasters. This study assesses the agricultural droughts in the Narmada River Basin (NRB), India, where more than 50% of the area is...

Loess-Like Dust Appearance at 40 Ma in Central China

Asian mineral dust has been studied extensively for its role in affecting regional-to global-scale climate and for its deposits, which enable reconstructing Asian atmospheric circulation in the past. However, the timing and origin of the dust deposits remain debated. Numerous loess records have been reported across the Asian continent with...

Coastal and seasonal hydrodynamics and morphodynamics of the Mekong Delta

Coastal retreat problems occur in many deltas over the world. Coastal features are not constant over time and are affected by sea level rise, river runoff, sediment supply, wave and tidal energy, underlying geology and climate. In addition, human activities profoundly influence the coastal processes as a result of changing natural patterns of...

Tidal Wave Propagation in the Flat Basin Under Wind Monsoon Climate

Tide is influenced due to not only mainly tide generating force but also local wind and weather patterns. The East Asian monsoons cause strong seasonal climatic variations in the Mekong Delta. A two-dimensional, barotropic numerical model was employed to investigate the dynamics of tidal wave propagation in the South China Sea with a...

Dry Feet

The growing population in urban areas around the world puts tremendous stress on natural resources. In India, the urban population has increased form 18 percent to 34 percent of the total population between 1960 and 2017 and is expected to exceed the rural population at the end of 2040. The growing urban population will putt stress on the...

Combining microwave and optical remote sensing to monitor rivers in monsoon affected regions

Understanding the river dynamics is very important to be able to make use of all river functions and to protect ourselves against floods. Hydrodynamic models are used to predict river behaviour and one of the input parameters is the river geometry. In-situ measuring of river geometry can be very expensive and time consuming. Remote sensing...

Moisture sources for East Asian precipitation: Mean seasonal cycle and interannual variability

This study investigates the moisture sources that supply East Asian (EA) precipitation and their interannual variability. Moisture sources are tracked using the Water Accounting Model-2layers (WAM- 2layers), based on the Eulerian framework.WAM-2layers is applied to five subregions over EA, driven by the ERA-Interim reanalysis from 1979 to 2015....

An Assessment of the Monsoon Water Situation in the Kathmandu Valley: Data collection and analysis of flow, water quality, land use and demand

Kathmandu, the capital of Nepal, is under increasing water stress. A rising water demand in the Kathmandu Valley is initiated by urbanisation with a rate of 4.7 % per year and amplified by a growing trend of per capita water consumption. At the same time, water availability seems to deteriorate. However, the severity of the problem is hardly...

Innovative rainfall measurement devices in tropical regions

In this thesis, the rain conditions of Yangon and Bago are studied. During the rainy season large rain quantities fall in a short period, which quite regularly causes major floods in Myanmar. The floods have a devastating impact on urban society, so it is important to address this problem. For forecasting these floods and designing a proper...

Holocene vegetation history and sea level changes in the SE corner of the Caspian Sea: Relevance to SW Asia climate

The palynological investigation of core TM (27.7 m long) taken in a dried out lagoon reveals both Holocene vegetation history in the north-eastern foothills of the Alborz Mountains and past water level changes of the Caspian Sea (CS). The delay in woodland expansion at the beginning of the Holocene, which is typical of eastern Turkey, the...

Morphological modelling of Lai Giang Inlet, Vietnam.

The Lai Giang inlet located in Binh Dinh province incorporates various features of the estuaries in the Central part of Vietnam. Belonging to the micro-tidal and wave-dominant coast and influenced by the monsoon regime, the inlet has a seasonal character. During the dry season, as the river flow diminishes, the wave action causes high level of...

Analysis of boundary conditions and concept design for port Dong Lam, Thua Thien-Hue Province, Vietnam

Introduction Dong Lam Cement Factory is developing a new clinker plant in Thua Thien-Hue Province, Vietnam. The clinker has to be exported towards Ho Chi Minh City, where it is grinded into cement and used for the construction industry. For the clinker production coal is needed and has to be imported. To make the in- and export possible a new...

Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system

Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system are investigated using numerical models. The ocean forcing including tidal and wave actions and sediment transport is simulated using Delft3D model. Fluvial processes in Delft3D are taken into account as results from SOBEK RURAL model. Analysis of the numerical simulation...

Sea breeze generated waves and coastal morphology

For the determination of the stability of coastlines, coastal erosion and the design of erosion protection studies, the “local” wave climate is the most important input parameter. For morphology, “local” means just outside the breaker line. On relatively calm days the local wave climate is strongly influenced by the effect of sea breeze. On the...
